Fun fact: Due to the gravity of mars, humans who stay on that planet have their bone density increase and they grow shorter. (Look it up, I am pretty sure it is true)
looked up, we'd grow taller, our bones would get less dense. My own knowledge backs up this fact
you're thinking of higher gravity wells, and (I think) mars has about 1/5 the gravity of the earth, so we'd become too tall.
Being discussed, been dismissed.
It's true. That's why the N'avi's in the movie Avatar are so huge. Also, people would be able to jump wicked high. (Until we evolved and got big)
Evolution is very long term. We'll have revlaimed Terra by the time it becomes a problem.
Also: no one's posted in logistics or modding for a while...
We wouldn't need to worry about getting very tall for hundreds or thousands of generations at a minimum, but bone density will be a problem within years.
